Dettagli di virus Autorun.ASE

Autorun.ASE is a worm that spreads by copying itself, without infecting other files.

It captures certain information entered or saved by the user, with the corresponding threat to privacy: passwords saved by certain Windows services.

Autorun.ASE prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

It uses stealth techniques to avoid being detected by the user:

• It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.
• It injects itself in running processes.
• It deletes the original file from which it was run once it is installed on the computer.

Autorun.ASE uses the following propagation or distribution methods:

• Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
• Computer networks (mapped drives): it creates copies of itself in mapped drives.
• Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
• File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.
